MAX306-MAX307

The MAX306/MAX307 precision, monolithic, CMOS analog multiplexers (muxes) offer low on-resistance (less than 100Ω), which is matched to within 5Ωbetween channels and remains flat over the specified analog signal range (7Ω, max). They also offer low leak-age over temperature (I NO(OFF)less than 2.5nA at +85°C) and fast switching speeds (t TRANS less than 250ns). The MAX306 is a single-ended 1-of-16 device,and the MAX307 is a differential 2-of-8 device.

The MAX306/MAX307 are fabricated with Maxim’s improved 44V silicon-gate process. Design improve-ments yield extremely low charge injection (less than 10pC) and guarantee electrostatic discharge (ESD)protection greater than 2000V.

These muxes operate with a single +4.5V to +30V sup-ply, or bipolar ±4.5V to ±20V supplies, while retaining TTL/CMOS-logic input compatibility and fast switching.CMOS inputs provide reduced input loading. These improved parts are plug-in upgrades for the industry-standard DG406, DG407, DG506A, and DG507A.

__________Applications Information

Operation with Supply Voltages

Other than ±15V

Using supply voltages other than ±15V will reduce the analog signal range. The MAX306/MAX307 switches operate with ±4.5V to ±20V bipolar supplies or with a +4.5V to +30V single supply; connect V- to GND when operating with a single supply. Also, both device types can operate with unbalanced supplies such as +24V and -5V. The Typical Operating Characteristics graphs show typical on-resistance with 20V, 15V, 10V, and 5V supplies. (Switching times increase by a factor of two or more for operation at 5V.)

Overvoltage Protection

Proper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maxi-mum ratings because stresses beyond the listed rat-ings may cause permanent damage to the devices.Always sequence V+ on first, then V-, followed by either the logic inputs, NO or COM. If power-supply sequenc-ing is not possible, add two small-signal diodes in series with supply pins for overvoltage protection (Figure 1). Adding diodes reduces the analog signal

range to 1V above V+ and 1V below V-, but low switch resistance and low leakage characteristics are unaf-fected. Device operation is unchanged, and the differ-ence between V+ and V- should not exceed +44V.
